As mentioned at the beginning of this section, here is the procedure to follow if you don’t get a
steady yellow light on power up. The absence of the yellow light means that for any reason,
the unit already has one or more codes in memory. You must erase these other codes to be
certain that the unit will operate only on the codes you plan to enter. Follow the steps shown
below.
Press the “Hard Code” button on the CPU board for one second.
Confirm slow flashing yellow LED
Press the Bell key (yellow flashing stops). Confirm two red flashes
Press the “Prgm Code” button on the CPU board for one second.
Confirm fast flashing yellow LED
Enter 8-8 followed by the Bell key (or wait 5 seconds). Confirm two red flashes
Extinguish the fast yellow flashing LED by pressing the Bell Key or waiting 30 seconds
This procedure has erased any Hard code that was present (see Section 4.1) and all user codes.
The yellow LED will usually come on steadily. If it doesn’t, it means that the unit has a previous
Program code in memory and this is no problem as you will be overwriting the old Program code.
Return to the beginning of this section for keypad changeable programming.
4.2.1 CHANGING THE USER AND PROGRAM CODE FROM THE KEYPAD
This is the day to day procedure that should be taught to the end user. Normally the end user
will not access the CPU board. Everything should be done from the keypad. To change the User
code:
Enter program code, followed by the Bell Key, note rapid yellow flashing LED (program
mode)
Enter prefix 0-1 followed immediately by a new 2-7 digit User code
Wait 5 seconds
Note two red LED flashes for confirmation, note rapid yellow flashing LED returns
Press Bell key to terminate program mode or wait 30 seconds
Re-enter new User code (door should open)
The program code should need changing much less often. To do it:
Enter old program code followed by the Bell Key, note rapid yellow flashing LED
(program mode)
Enter prefix 0-0 followed immediately by a 5-7 digit new Program code
Wait 5 seconds
Note two red LED flashes for confirmation, note rapid yellow flashing LED returns
Press Bell key to terminate program mode or wait 30 seconds
Re-enter new Program code followed by the Bell Key (to test it), note rapid yellow
flashing LED returns
Press Bell key to terminate program mode or wait 30 seconds
The logic behind this procedure is as follows. All programming for the DK-26 starts with putting
the unit into program mode (except entering the single Hard code). The unit is put into program
mode by either pressing the “Prgm Code” button on the CPU board or entering a valid program
code. When you enter a program code, however, you have to terminate the sequence with
the Bell Key. This is for a little extra security. An unauthorized person who came across a
copy of the Program code might not know he had to press the Bell key after entering it. The
prefix 0-0 causes the code which follows to be stored as the Program code. The prefix 0-1
causes the code to be stored as a user code.
4.2.2 ADDING MULTIPLE USER CODES
The DK-26 has memory locations for up to 59 User codes. This allows separate codes for
individuals or groups which is a benefit because when one code is changed (usually owing to a
security worry), the people who use the other codes don’t have to learn a new code. To
